The Open Relay DataBase is closing down, after five and a half years of supporting the fight against spam. The use of networks of compromised PC’s has made ORDB less useful in recent years, and the volunteer staff acknowledged this in their farewell message on the ORDB website, “the general consensus within the team is that open relay RBLs are no longer the most effective way of preventing spam from entering your network as spammers have changed tactics in recent years, as have the anti-spam community.”
The website is scheduled to disappear by 31 December 2006.
